java - 带有 JSON : Not working 的 Spring 3.1 REST

Question

一旦我将我的测试应用程序移动到一个生产性(？)应用程序并开始在 Tomcat 上进行测试，我基于 Spring 3.1 的 REST 服务就停止工作了。虽然显示了默认的 index.jsp，但我的应用程序 (http://myhost:myport/test-webapp/myrestservice) 无法访问，我得到 The requested resource (/test-webapp/myrestservice) is not available.

这是我做的:

Controller :

package com.test.webapp.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

import com.test.webap.entity.Account;

@Controller
@RequestMapping("/myrestservice")
public class AccountController{

@RequestMapping(method = RequestMethod.GET, produces="application/json")
@ResponseBody
public Account getEntity() {
            // ... <simplified>
    return new Account(//...);
}
}

调度 Servlet 配置:

package com.test.webapp.web;

import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.ServletRegistration;

import org.springframework.web.WebApplicationInitializer;
import org.springframework.web.context.ContextLoaderListener;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
import org.springframework.web.servlet.DispatcherServlet;   
import com.test.webapp.config.AppConfig;

public class AppInit implements WebApplicationInitializer {

    private static final String DISPATCHER_SERVLET_NAME = "dispatcher";

    public void onStartup(ServletContext container) throws ServletException {
        // Create the dispatcher servlet's Spring application context
        AnnotationConfigWebApplicationContext dispatcherContext = new AnnotationConfigWebApplicationContext();
        dispatcherContext.register(AppConfig.class);

        // Manage the lifecycle of the root application context
        container.addListener(new ContextLoaderListener(dispatcherContext));

        // Register and map the dispatcher servlet
        ServletRegistration.Dynamic dispatcher = container.addServlet(
                DISPATCHER_SERVLET_NAME, new DispatcherServlet(dispatcherContext));
        dispatcher.setLoadOnStartup(1);
        dispatcher.addMapping("/");

    }
}

配置类:

package com.test.webapp.config;

import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@Configuration
@ComponentScan( basePackages = {"com.test.webapp.controller"})
public class AppConfig{
    // Nothing here. Once I start using the beans, I will put them here
}

而且，web.xml 中的内容并不多:

<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <display-name>Test Web App</display-name>
</web-app>

在我的项目中除此之外别无其他。我错过了什么吗？旧项目更像是记录传入的 JSON 请求等(现在已删除)正在运行，但我不再拥有它了:(所以，很多新手忧郁症。请在这里帮助我。非常感谢! !

您在生产环境中使用的是什么版本的 Tomcat？看来您需要 Tomcat 7 才能获得支持您的 WebApplicationInitializer 所需的 Servlet 3.0 规范实现。
